Outdoor or ambient air pollution is a critical environmental problem causing millions of premature deaths in Asia. At the same time, indoor air pollution is a major challenge also causing millions of premature deaths. The nature of indoor air pollution varies from one region or one country to another depending on the climatic conditions, type of housing, socio-cultural background and others.

In Metro Manila, the capital city of Philippines, given the warm tropical climate and high population density, indoor air pollution challenges mainly entail: cooling, air circulation and ventilation systems; fumes generated from cooking, cleaning agents, paint and other chemicals used for construction, repair and maintenance indoors; emissions from use of generators for the supply of electricity; emissions from vehicles (in enclosed parking spaces).

In addition to reducing the emission of pollutants, indoor air quality management must also consider controlling the spread of communicable diseases spread by viruses, bacteria, fungi or parasites. The outbreak of COVID-19 has re-emphasized the importance of preventing the spread of communicable diseases inside buildings. With the easing of lockdowns and gradual return to business under the new normal it will be important to reassess and revamp indoor air quality management and general health and safety conditions inside buildings.

This webinar was a targeted training program for the members of the Ortigas Center Association, Inc. (OCAI). The training informed the participants on:

1. General concepts of Air Pollution

2. Managing indoor air quality under the new normal

3. Key features for controlling the spread of communicable diseases such as COVID-19
